CHANGE IN RATINGS

Corn Products

upgraded at Citigroup: CPO was upgraded to Buy, Citigroup said. $31 price target. Odds are increasing of another HFCS price increase in 2007. Maintaining above-consensus earnings estimates.

Disney

downgraded at Citigroup: DIS was downgraded from Buy to Hold, Citigroup said. $32 price target. Stock has made a good rally, and the company could struggle to achieve 2007 earnings estimates. Park attendance could be soft, on a difficult comparison from the 50-year anniversary promotion.

Genzyme

upgraded at Merrill: GENZ was upgraded to Buy, Merrill Lynch said. $74 price target. Company could post weak second quarter results, as competition is heating up. Recent acquisition could also dilute earnings.

Global Crossing

upgraded at Jefferies: Jefferies said it is upgrading GLBC to Hold from Underperform due to the company's improved liquidity position and expected positive 2007 EBITDA. Price Target of $20.

Public Service Enterprise

downgraded at Citigroup: PEG was downgraded from Buy to Hold, Citigroup said, $68 price target. Still waiting on approval for the EXC deal, which will no longer be binding after June 20.

PMC Sierra

upgraded at Morgan Stanley: Morgan Stanley said it is raising its rating on PMCS to Equalweight from Underweight. Management has so far successfully implemented a diversification plan leveraging the company's core competencies and, when combined with the recent improvement in its valuation, offers a balanced risk/reward.

Tellabs

downgraded at Deutsche: TLAB was downgraded from Buy to Hold, Deutsche Bank said. $17 price target. Estimates also raised, though the bar is set very high for the second half of the year. Could also lose some VZ market share in 2007.

Wellcare Health

downgraded at CIBC: WCG was downgraded to Sector Perform, CIBC said. Stock has reached the $50 price target, and is trading at an 18% premium to its peers.
